HYDHQCARBON-BURNEH.

SPECIFICATION forming part of Letters Patent No. 766,884., dated August9, 1904:.

Application filed A gust 31, 1903. Serial No. 171,445 (No model.)

To Ml whom it may concern:

Be it known that 1, JOHN A'rkINsoN HUNT, a citizen of the United States,residing at Boston, county of Suffolk, and Commonwealth ofMassachusetts, have invented certain new and useful Improvements inHydrOcarbon-Burners, of which the following is a specification.

This invention relates to an improvement in apparatus for vaporizing oiland water, mixing the two, and superheating the mixture for combustion;and it consists in certain novel features of construction more fullydescribed hereinafter.

In the drawings, in which like letters of reference indicatecorresponding parts throughout, Figure l is a side View of the burnerand easing. Fig. 2 is a plan view of the burner removed, and Fig. 3 is aview of the casing.

V is a vaporizer consisting of parallel tubes connecting at one end withtubes V and V which supply them, respectively, with water andhydrocarbon. These tubes V and V, which supply them, are connected withsup pl y tanks of any known construction controlled by valves S and S.

The vaporizing-tubes enter the mixer M at one side and in the samedirection.

G is a gas-pipe located out of line with the vaporizing-tubes, whichconducts the mixed gases from the mixing-chamber M to the burner-pipe B.By this arrangement of the tubes and pipe the water and hydrocarbonvapor are forced into M and against its opposite walls, from which theyare baiiied back and thoroughly mixed without the liability of excessivepressure in one vaporizer overcoming that of the other and forcing backthe vapor therein and of the gases passing directly through the mixerwithout being properly united. I A is a coupling uniting G and B, havingopenings (0, through which air is drawn.

7) is a burner-nozzle for deflecting the flame down against the pan P,which forms the panbottom of the casing C. From this it is thrown upagainst and through the vaporizing-tubes and against the mixer M. Theend walls of the casing C are notched to receive the pipes G' and V andV as at C and the faces of the recess are roughened, as at 0, so thatthe pipes when laid therein are tightly held. The vaporizing-pipes V andV being spaced apart yield slightly and when pressed into the notch bindagainst its roughened sides and are [irmly held, as stated above.

The cover I) is suitably perfo 'ated and is usually cast in one piece,as is also the other portion of the casing.

From, the oil-pipes above the valve S is a pipe which leads to the pan Pand has a controlling-valve o therein, which regulates the supplythrough it.

The operation of the burner is as follows: Asmall amount of hydrocarbonis aliowed to How into the bottom of the pan, and the same is thenignited. As this heats the tubes V and V the valves S and are opened toad mit a supply of hydrocarbon and water, which is vaporized in the nowhot tubes. From these the gasespass to the mixer M, where they arethoroughly mixed. Then this mixture passes through the pipe G and intothe coupling A, where it receives the airsupply, and from which itpasses through B to the burner l), which being lighted will throw itsflame against the bottom P of the casing (J, where it is baffled backupon the vaporizer, so that the process is made continuous.

The box 0 and the mixing-chamber are usu ally castings, and the vaiiorizingtubes are tapped directly in the mixing-chamber M, so that theconstruction is exceedingly simple When the vaporizer is laid inthe box,the pipes V and V and G- project through the openings C, which by theirV-shaped walls support and securely hold the burner, so that nofastenings are required.

The burner may be started up by other means, of course, than the oil-supply 0, and the ai r-supply A may be omitted without affecting theoperativeness of the machine; but both of these features are preferred,as they increase the effectiveness of the burner and the ease with whichthey are operated. The number lel but adapted to yield slightlylaterally and a support having a substantially V-shaped recess toreceive and hold said tubes.

8. The combination of a hydrocarbonburner having tubes heldsubstantially parallel but adapted to yield slightly laterally and asupport having a substantially V-shaped recess to receive said tubes,the faces of said recess being roughened to hold the same.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN ATKINSON HUNT.
